Gosh, yes! I just thought this would be a good place to start. It's nice for students (at least mine) to get comfortable with all the dominant 7 chords/scales first.
I'm thinking of adding a "Parker Blues," a standard jazz blues and maybe some minor blues too, in all 12 keys of course. That may have to wait until Christmas break though.
Thanks for checking them out, and please pass along to folks who might benefit from working these simple blues progressions out.
